Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Chevrolet Colorado Owner Comments

problem #1

Dec 152010

Colorado LS 3.5L

  • Automatic transmission
  • 48,000 miles


I understand that I've owned the vehicle for almost 7 years , but I didn't have any problem with the transmission until they replaced the head last year and I took it back because the "Check Engine" light was on and I could smell Engine Oil burning "leak" but the dealer told me the trans. was leaking (It never leaked prior) and after working in a dealership service dept. for 24yrs. I know burning trans. fluid smells different than engine oil.The "Check Engine" light was on and they said it needed an "Emission Purge Solenoid" , note I had taken the truck in several times for the light being on and after paying the $100.00 diagnostic fee they told me I didn't know how to put on a gas cap . Now I admit the gas cap on this rig is a real piece of sh*t but each time I purchased a new cap.I also admit I have to remove the gas cap more than normal because the truck gets such shity gas mileage,but I think I know how to put it on properly.
